In a large bowl, add in the whey protein and oats.Stir in the peanut butter, and mix until it starts to come together.Add in the honey and vanilla. Continue to stir until it comes together some more. Add in the milk and stir until almost combined. Then add in the chocolate chips and raisins.Note: Cutting into shapes is more time consuming, so by all means, if you want to skip that and cut into 16 bars, go for it!Form dough into a 9x9 square pan. Using whatever cookie cutter you want (I used a star), press into shapes and remove with a spatula. I placed all mine in small ziploc bags. Once you cut out whatever you can, press the remaining dough into half of the pan, so it remains the same thickness. Keep cutting shapes and removing the bars and pushing over the dough to one side until you have no dough left.Store each bar in a plastic baggie and keep stored in the freezer. Can be eaten directly from the freezer. They soften up in a few minutes.
